Avalanche Summary

You could trigger an avalanche where strong winds formed cohesive slabs over weak layers. Avalanches will be larger and more dangerous on north to northeast through east slopes where wind drifts are deepest. Avoid shallow trigger points like buried rocks or trees, convex rollovers, or the edges of slopes where the slab is the thinnest, and bypass travel on hard, hollow-sounding snow on steep slopes.

You can find safer travel on slopes less than about 35 degrees in steepness.
